GOTTN-PICKER.

Specification' of Letters Patent.

Application filed September 20, 193.5. Serial No. 51,681.

To all whom it may concern Be it known that @Lann citizen of the United States, and a resident of Memphis, in the county of Shelby and State of Tennessee, have invented certain N. IWISNER, a

new and useful Improvements in Cotton- Pickers; and l do hereby declare the follow# ing to be a full, clear, and exact description of th'e invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

This invention relates to improvements in cotton pickersone object of the invention being to provide simple and efficient means enable him to readily reach the bells on all parts of growing plants, without necessity of bending his body to unnatural and un' comfortable positions, and to thus simplify and decrease the labor of cotton picking.

lill/lith these and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in. the claims ln the accompanying drawings;.Figures l `and 2 are transverse sectional views of a picker head embodying my improvements, and showing, respectively, different positions assumed by the picker pins or ngers during the operation of the device; Fig. 3 is a longitudinal sectional view, partly in elevation, and Fig. e is a transverse sectional view illustrating a modification.

The frame of the picker head comprises two end plates l, 2, spaced apart and connected by bars 3, 3. The end plates are made with openings 4 in which a suction tube 5 is fitted, said suction tube extending beyond one end of the frame -for connection with suitable suction apparatus and a receptacle (not shown) and the portion of the suction tube extending rearwardly from the end plate acting as a handle for the picker head. y

The suction tube is made with an opening 6 which extends approximately from one end plate to the other to receive cotton from the picking devices,

Y ber of fixed pins 8 may be employed to In constructing the picking devices, ll ern- .ploy two shafts 7, 7, carrying picker pins 8,

9, projecting' in opposite directions from each of said shafts-the pins 8 being rigidly secured to the shafts 'and the pins 9 being carried by collars l() mounted loosely on said shafts. One of the shafts 'T carries a greater numberof pins than the other and the pins of one shaft inter-mesh with those of the other shaft as shown in Figs. l and 3, during the picking operation.

A tube 1l surrounds each shaft 7, in a manner to be capable of movement laterally at right angles to the axis of the shaft, said tube being made with perforations through which the picker pins 8, 9, pass freely, so that when the shafts 7 are rotated, the tubes l1 will also be rotated. Any desired nurninsure proper rotation of the tubes when the shafts are rotated, and by mounting some of the picker pins (as the pins 9) loosely on the shaft, so that they may pass freely through the-holes in the tubes without appreciable pressure against the walls of the holes, the friction between the pinsiand tubes will be reduced. Each tube ll of the picker devices is provided in its respective heads with elongated slots 1Q to receive pins 13 (having rollers 14; thereon) secured to the end plates of the frame, so that when the shafts 7 and tubes l1 are rotated (in opposite directions) lateral motion at right angles to the axes of the shafts, lwill be imparted to the tubes l1 and cause said tubes to more over the inwardly projecting pins and strip the cotton from the same during the movement of said inwardly projecting pins from the positions shown in Fig. l past the positions shoivn in Fig. 2,-during which movement of the pins, over the opening 6 of the suction tube, the picked cotton will be deposited into the latter.

nstead of the 1'ollerand-pin construction shown in Figs. l and 2 for stripping the cotton from the picker pins, i may employ cams l5 carried by plates i6 secured to end plates of the picker head and operating in elongated slots in the ends of the tubes 11 as shown in Fig.

During the rotation of4 the picker de'- rices and whenthe tubes move inwardly to expose the outwardly projecting picker pins, the latter will pass between guard lfingers 17 secured to the connecting bars 3 littv of -the picker head and projecting over the tubes ll'in a manner to prevent the entrance of trash, leaves, etc., into the picker head.

The outer ends of the shafts 7, 7, project beyond their bearings in the end plate 2 of the head, for the reception of the intermeshing gears 18, 19,-said gears being disposed within a housing 20 secured to the end plate Q. A iexible shaft 21 is coupled with one of the shafts 7 as shown in Fig. 3 and re ceives motion from any suitable source of power. By thus gearing the shafts 7 together and applying motion to one of them, the picking devices will be operated to effectually pick the cotton from the bolls and deposit the samepinto the suction tube, without danger of clogging the picker head or permitting the passage of trash, etc., to the suction tube.

Various slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope and hence l do not wish to restrict myself to the precise details `herein set forth. l

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. In a picker head, the combination with a frame, two shafts mounted therein, and

picker pins carried by said shafts, of latframe comprising two end plates spaced1 apart and each having an opening therein, a suction tube mounted in the openings in the end plates and having an elongated opening between said end plates, shafts mounted in the end' plates, picker pins carried by said shafts, laterally andv revolubly movable tubes surrounding said shafts c:ind having perfor-ations for the passage of the picker pins, means for rotating said shafts, and means for moving the tubes at right Maaate for rotating said shafts, of picker pins rigid with said shafts, picker pins loosely mounted on said shafts, tubes surrounding said shafts and having perforations for the passage of all of said picker pins, and means for moving said tubes parallel 'to a plane at right angles to the axes of the shafts when the latterand the picker pins lare rotated.

,o a., In a picker head, the combination of a frame comprising end plates and bars connecting sa'id end plates,- shafts mounted in the end plates, means for rotating said shafts, picker pins carried by said shafts, laterally and revolubly movable tubes loosely surrounding lsaid shafts and having perforations for the free passage of the picker pins, means for moving said tubes in directions at right angles to the axes of the shafts, and guard lingers secured to the connecting bars of the frame and projecting between thepiclrer pins and over said tubes.'

5. in a picker head, the con'ibination of a flame comprising two end plates spaced apart and each having an opening therein, a suction tube handle mounted in the openings in the end plates, the suction tube handle' extending rearwardly from the luc-ker head and adapted to serve as a conveyr-r for cotton and cotton seed to a given point, shafts mounted in the end plates, picker pins carried by said shafts, laterally and revolubly movable tubes disposed between the end plates and having elongated slots in their ends, surrounding said shafts and having perforations for the passage of the picker pins, means for transmitting motion tosaid shafts, and means cooperating with the slotted ends of said tubes for moving the tubes parallel to a plane at. right angles to the axes of the shafts for stripping thex picker pins.

in testimony whereof, l have signed this specification in the presence of :wo subscribing witnesses.
